IMPROVEMENT IN GLOBE-VALVES.

Hrs-

The Schedule referred to in these Letters Patent and making part vof thesame.

To all whom it may concern Be it known that I, ISAAC W. BROWN, of Jeer-4son City, in the county of Coleand'St-ate of Missouri,

have invented a new and 'improved Globe-Valve; and I do hereby declarethat the following is a full, clear, and exact description thereof',which will enable others skilled in the art to make and use the same,reference being had to the accompanying drawings forming part of thisspecication.

The object of this invention is to provide an arrangement ofglobe-valves whereby the valves may be ground to their seatsl at anytime while in position, and whereby any obstruction getting onto thevalveseat may be readily removed.

The drawing represents a sectional elevation of a globe-valveconstructed according to my improvement..

The shell and valve-seat are constructed similar to those now in use.

My invention consists in constructing on each of the stems A and C ahand-wheel, separated by extending the stem O, after it passes throughthe hollow stem A, a `suflicient distance to enable a man to hold awheel in each hand, allowing him to loosen and tighten the lower wheelwith one hand, whilst at the Sametime with the other hand he can operatethe upper wheel for grinding the valve B on its seat.

This invention will obviate the use of monkeywrenches, 8vo., andfacilitate the grinding of valves on their seat-s,^and the lengthencdspring D will give the stem C an easynpward motion whilst the grindingprocess is taking place.

I claim the two hand-Wheels on the stems Aand C, when separated asui`cient distance to enable a man to give motion to the stern A` withone band, and at the same time give a dierent motion to the stem O withthe other hand, when constructed and combined with the spring D and thevalve B, for the purposes set forth.

ISAAC W. BROWN.
